Class C rear end sag and banging!
Just got back from a 4,000 mile plus journey to the great northeast - had a great trip and for the most part a pretty uneventful RV time. I have a '93 29ft Class C on a Ford E350 chassis with the 4...

I'm not sure what I would be looking for and what would be a good swap - are you saying that most leaf springs - even from a later model 450 will fit my E350 chassis?? How many leafs should I be looking for?
Not opposed to the salvage yard route (love going to my local Pull-a-Part), but I just don't know what I'm looking for.
Yes, just find any E450. They all have the same 9450 spring rate, so that makes it easy. Just find the newest set you can. They did offer the E450 with varying leaf numbers over the years, but it doesn't matter since the spring pack rating was always the same. I'd try to find something lower mileage so they won't already be tired, and try to find a set from a body that isn't also over loaded (i.e., take a set from a shuttle bus or box truck rather than a motorhome).
You could go with newer E350 springs, but you'd still likely be overloading them. And since they came with RAWRs from 6,080 to 8,500 pounds, finding the set you want will be harder than just using an E450 set.
From '92 to '19 models, all E-series cutaways have the same spring mounts, so that makes it super simple.
